I have a Fedora Core 4 system running with a GeForce 5200 (AGP, 128MB, XFX). I have installed the drivers with RPM as described on http://www.fedorafaq.org/#nvidia , and it has worked well.

I now tried to swap this card with a GeForce 6600 (128MB, Gainward). The text-mode part of the boot process looked normal, but when I should have seen X in graphic mode (1600x1200, 60Hz) I just got some funny stripes.

I swapped back to the 5200 and all is well. Any ideas what I need to do to make the 6600 work?

Are you certain that you're using the nvidia driver? Can you generate a bug report while the 'funny stripes' are on the screen?

Thanks for your reply. I am sure I am using the driver installed as described on http://www.fedorafaq.org/#nvidia, I could clearly see the improved performance with the 5200 card after it was installed. Unfortunately I am a novice on this, and I don't know how I could generate a bug report. I saw mention of the script `nvidia-bug-report.sh` and the file /var/log/nvdia-installer.log here, but none of them exist on my system.

janeri,
The root user should have nvidia-bug-report.sh in its $PATH. If you can't just run 'nvidia-bug-report.sh' then something is either broken in your nvidia driver installation or you don't have the nvidia driver installed. Running nvidia-bug-report.sh will generate an nvidia-bug-report.log.

I'd suggest installing the official nvidia driver package from the nvidia website. That will assuredly provide `nvidia-bug-report.sh` once the driver is installed.

It seems the Fedora Core 4 (FC4) RPM's is somehow not "complete" nvidia drivers - I was root when looking for the mentioned files, but they are not present anywhere on my system. If no other solution surfaces I will try removing the FC4-nvidia drivers and install the ones from http://www.nvidia.com/object/unix.html instead

Thanks for notifying me, yes this really looks like a very similar problem. It will be interesting to hear if it helps to use another BIOS (I replied in that thread too, before I realised it was yours).
